FRU lT-EVAPO RATO R.

SPECIFICATION forming part of Letters Patent No. 552,981, dated January 14, 1896.

Application tiled July 27, 1895. Serial No. 557,365 (No model.)

To @ZZ whom, it may concern:

Be it known that I, WILLIAM BOLINGER, a citizen of the United States, residing at Eureha, in the county of Greenwood and State of Kansas, have invented a new and useful Fruit-Evaporator, of which the following is a specification.

This invention relates to an improvement in fruitevaporators, and has for its object to provide a simple, inexpensive and etlieient evaporator adapted especially for family use, being designed to be placed upon an ordinary cooking-stove.

The principal objects in view are to provide in connection with a fruit-evaporating compartment having a surrounding hot-water space or chamber a foraminous tube leading from the interior of the evaporating-compartment to the exterior, and providing for the proper ventilation of said compartment and the carrying off of the excess steam contained therein; also, to provide in connection with the hotewater space or chamber a steanrtube carrying a whistle and disposed in such manner that said whistle will be blown when the water-level has descended to a predetermined point.

Other objects and advantages of the invention will appear in the course of the ensuing description.

In order to accomplish the objects above enumerated, the invention consists in an improved evaporator, embodying certain novel features and details of construction and arrangement of parts, as hereinafter fully set forth, illustrated in the drawings, and finally incorporated in the claims.

In the accompanying drawings, Figure l is a perspective view of an improved evaporator constructed in accordance with this invention with the door thereof thrown open to show the interior arrangement. Fig. 2 is a vertical transverse section through the same with the door closed.

Similar numerals of reference designate correspondingT parts in the several figures of the drawings.

Referring to the drawings, l designates the body of the evaporator, which is preferably made in a substantially cubical form and provided throughout with double walls of tin,

copper or other sheet-metal, said walls being so disposed as to forni an inclosed inner compartment 2 and a surrounding hot-water space, as shown. The space between the bot tom of the compartment 2 and the bottom of the evaporator-body is preferably greater than the space between the side, end and top walls, in order to provide the necessary space for an ample supply of water for a purpose that will hereinafter appear.

Nithin the evaporator-compartment are arranged a number of cleats or ledges 3,which are oppositely disposed in pairs andadapted to receive a number of fruit-holding trays i, said trays being formed from perforate sheet metal and provided at their front edges with suitable handles 5, facilitating the insertion and removal of the trays through the doorway.

G indicates a drip-pan made of imperforate sheet metal and of a size adaptin g it to beintroduced into the evaporating-compartment upon the floor thereof, and beneath the fruitholding trays in such position as to catch the drip from the fruit, said drip-pan being capable of being removed the same as the other trays whenever necessary. When all the trays and the drip-pan are in place within the evaporator-compartment, the latter may be closed by means of a hinged door 7, the latter being engaged by a spring-metal keeper 8 secured to the front wall of the evaporator and serving to hold said door snugly and firmly closed, so as to effectually prevent the escape of steam from said compartment.

9 designates a ventilator-tube which is pref erably arranged in the rear of the evaporator'- compartment and supported against the rear wall thereof. This tube is composed of foraminous sheet metal and extends from top to bottom of said compartment, passing through the top of the evaporator-body and extending a suiiicient distance above the same to receive a cap l0. The upper portion of this tube, or that portion which projects through the space between. the upper walls of the evaporator and above the saine, is made imperforate, as shown, and the cap lO is also imperforate and adapted to iit snugly over IOO the upper end of said tube so as to prevent the escape of steam when in place. Tater is introduced between the double walls of the evaporator and into the lower boiler-chamber thereof through a nozzle 1l, arranged prefn erably at one of the rear corners of the evaporator and threaded to receive a screw-threaded cap l2, having formed therein one or more perforations providing for the escape of the steam.

13 indicates asmall pipe which communicates with the hot-water space through the outer wallet' the evaporator-body and is provided at its extremity with a steam-whistle 14. When the water gets below a certain level in the evaporator `or that point where the tube 13 enters, the steam will enter and pass through said tube and blow the whistle referred to, thus warning the attendant that the water-supply needs replenishing.

From the foregoing description it will be apparent that a very neat, simple, and inexf pensive fruit-evaporator is obtained, which may be made either of a size for family use or in larger sizes for factories, rte.

' In operation water is introduced into the boiler-chamber and between the double walls of the evaporator, the screw-cap l2 applied and the device placed upon the stove. The trays containing the fruit are now introduced into the evaporator-compartment and the drip-pan placed beneath the saine and the door closed. As the water boils, the heat therefrom entering the evaporator-compartment will cause the fruit to sweat and the juice therefrom to descend into the drip-pan. Y

By reason of the fruit-trays being made of Vperforate metal the heat and steam are aldue wai-nin g of the same willbe given through the medium of the whistle above described.

One or more of the trays may be removed at any time when the fruit therein has been sufficiently evaporated and replaced by trays of fresh fruit, thus rendering the device very convenient in practice.

Various changes inthe form, proportion. and minor details of construction may be resorted to without departing from the spirit or sacriiieing any of the advantages of this invention Vsubstantially as and for the purpose described.

2. The herein described evaporator, comprising a body having an inelosed evaporaring lchamber entirely surrounded byV a hor water and steam space, means for supporting a series of removable fruit trays within said chamber, a foraminous `ventilator tube are ranged wholly within said chamber and hav- 1n g an imperforate portion or extension passing through the steam space of the ventila- Y tor body, and a cap for sealing or closing the outer end of said ventilator tube, substantially as and for the purpose specified.

ln testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

VILLIAM BGLNGER.
